  • Method for operating motor vehicle internal combustion engine
    Patent number: 9458799
    Abstract: A method for operating a motor vehicle internal combustion engine that has an exhaust tract with an exhaust gas purification unit acting catalytically and/or by filtration with which combustion air supplemented by exhaust gas diverging from the exhaust tract is fed to the combustion chambers of the internal combustion engine by exhaust gas branching off from the exhaust tract at a total exhaust gas recirculation rate. The total exhaust gas recirculation rate has a low-pressure proportion diverging downstream from the exhaust gas purification unit and a high-pressure proportion diverging upstream from an exhaust gas turbocharger turbine arranged in the exhaust tract. An essentially decreasing low pressure proportion is set with at least approximately the same operating points of the internal combustion engine with an increasing operating period of the exhaust gas purification unit.

  • Method and device for operating functions displayed on a display unit of a vehicle using gestures which are carried out in a three-dimensional space, and corresponding computer program product
    Patent number: 9440537
    Abstract: A method to control functions displayed on a display unit of a vehicle uses gestures carried out in three-dimensional space. When a first gesture carried out in three-dimensional space is detected it is determined whether the detected first gesture is allocated to an activation of an operation of a function. If it is determined that the detected first gesture is the gesture allocated to the activation of the operation of the function, then the function is activated. Next a second gesture carried out in three-dimensional space is detected and it is determined whether the detected second gesture is a gesture allocated to the operation of the function. If it is determined that the detected second gesture is the gesture allocated to the operation of the function then the operation of the function is performed.
